Given numbers are 781,789,143,213,702
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,789,143,213,702 is 144192906.
Find LCM of 781,789,143,213,702 with Prime Factorization
| 3 | 781, 789, 143, 213, 702 |
| 11 | 781, 263, 143, 71, 234 |
| 13 | 71, 263, 13, 71, 234 |
| 71 | 71, 263, 1, 71, 18 |
| 1, 263, 1, 1, 18 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 13 x 71 x 1 x 263 x 1 x 1 x 18 = 144192906
Therefore, the lowest common multiple of 781,789,143,213,702 is 144192906.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
781 x 789 x 143 x 213 x 702 = 13175915171562
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
781 : 1, 11, 71, 781
789 : 1, 3, 263, 789
143 : 1, 11, 13, 143
213 : 1, 3, 71, 213
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,789,143,213,702, is 1.
Now, the common factors can be found like this.
781:11x 71
789:3x 263
143:11x 13
213:3x 71
702:2x 3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11x 13x 71 = 91377
Therefore, the value for common factors is 91377.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 13175915171562/(1x91377)
LCM = 13175915171562/91377
LCM = 144192906
Thus, we can understand that the LCM of 781,789,143,213,702 is 144192906.
